When the FORTRAN programming language debuted in 1957, it transformed how scientists and engineers programmed computers.

Abstract: This article shows how to model the voltage response of a battery excited by a piecewise constant current source. Modeling is done both by using a mathematical approach based on an ...

If a piecewise constant function is integrated, the result is okay, if 2 integrals are nested, that's okay too, but 3 times the result is 'nan' which it shouldn't be: from sympy import * a1, a2, a3 = ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

When running the python example python/gtsam/examples/OdometryExample.py I came across the an issue on OdometryExample.py:65 in the usage of gtsam_plot.plot_pose2 ...

We conclude the previous tutorial on topological insulators by proposing the analytical expression of a phenomenological potential energy capable of simulating the surface states of electric charge.
